5-Bromo-2-(3-bromo-5-(4-fluorophenyl)-1H-pyrazol-1-yl)-4-(4-bromophenyl)thiazole CAS 956185-38-9

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

CATO supplies 5-Bromo-2-(3-bromo-5-(4-fluorophenyl)-1H-pyrazol-1-yl)-4-(4-bromophenyl)thiazole (CAS 956185-38-9), a certified reference material (molecular formula C18H9Br3FN3S, MW 558.06 g/mol) for analytical method development and quality control.

Based on its molecular formula C18H9Br3FN3S, 5-Bromo-2-(3-bromo-5-(4-fluorophenyl)-1H-pyrazol-1-yl)-4-(4-bromophenyl)thiazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 558.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
